The Warner Archive July 30, 2019 DVD release of the noir romcom "Double Danger" (1938) makes it great fun to figuratively go back to the movies. This glee begins with true-crime novelist/perpetrator Bob Crane sharing the name of the actor who plays titular undercover POW Robert Hogan in the '60scom "Hogan's Heroes." The "Hogan" analogy continues with the reel Crane reveling in an ongoing cat-and-mouse game with friend/police Inspector David Theron.
The doll who provides the "rom" is jewel-thief Caroline Martin; she is another mouse with whom Crane can play.
Our story begins with a cocky Theron telling angsty jeweler Gordon Ainsley "trust me; I know what I'm doing" as to especially precious diamonds. Thus begins our tale in which this ice is a hot potato throughout the film.
Martin begins the game via a successful ruse that gets her custody of the loot until Crane pulls a trick that results in his adding a new link to the chain of custody. One lesson here is that there is no honor among thieves.
The plot thickens on Martin and Crane unexpectedly reuniting at a weekend house party at the stately home of Theron. The ruse here is that Theron strongly suspects that one of his guests is the jewel thief known as "The Gentleman" but must obtain direct evidence before bestowing a pair of bracelets on that malfeasor.
Comic relief is provided in the form of flighty teen daughter "Babs" Thornton and her would-be suitor Roy West (Arthur Lake of the "Blondie" film and television series). The complication there is that Babs only has eyes for sophisticated older man Bob.
The final piece of the puzzle this time is that Theron has Ainsley essentially literally crash the party with a duplicate set of the diamonds that provide one meaning to the title of "Danger."
The bedroom farce in this Code-era film comes in the form of Crane and Martin rotating the two sets of diamonds between themselves in an effort to implicate the other. This leads to a classic drawing-room confrontation that does not go as Theron plans. The lesson here is the one that every thief knows; part of a plan is the plan going awry.
More hilarity ensues until everyone gets what amounts to a happy ending in this film that expertly keeps several plates spinning in a tale that expertly blends comedy and pulp fiction.
